Facebook Walls Full of Profanity

Do you use cuss words on Facebook? If so, you're not alone, as a new study shows. According to scans of some 30,000 Facebook walls by Reppler, the company found that half of all Facebook walls are covered with profanity. This matters because more and more employers are looking at social networking sites of potential employees as part of the hiring process.

According to Reppler's findings, 47% of users have profanity on their Facebook wall and 80% of those with profane terms have a post or comment with profanity from a friend. Also, 56% of all posts with profanity come from friends on Facebook. The most common nasty word is the f-word, followed by the s-word.

If you want to have your friends say what they want on your wall and not allow perspective employers (or anyone else who you're not friends with, for that matter) see all the profanity and vulgar language, it is suggested that you lock down your wall so only your Facebook friends (those you've approved) can see your wall. Otherwise, tell posters on your Wall to keep it clean.

YouTube Celebrates 6th Birthday, Reports 3 Billion Views Daily

YouTube, the ever popular online video platform, turns 6 years old today. The once independent video platform was snapped up in 2006 and has continued to grow at an alarming pace as retailers, independent video producers and film makers flock to the video platform. There are a few notable competitors such as Vimeo and, but YouTube's dominance in online video is astonishing.

YouTube is reporting 3 billion video views per day. Also, just in the last 12 months, YouTube says it's daily video views have increased 50%, indicating that growth is recent and solid. To put these astonishing numbers into perspective, it's as if almost half the world's population watching a YouTube video each day or every U.S. resident watched at least 9 videos each day.

Another crazy number: 48 hours of video is uploaded to Facebook every single minute, which is up 100% year over year. However you slice it, YouTube is a sensational tale of usage, stickiness and sheer volume. Are you a YouTube viewer? Do these usage figures resonate with you in any way?

Twitter Starts Email Notifications

How do you keep up with activity on Twitter?  That is -- if someone sends you an @ reply, do you ever know? If you utilize a client such as Tweetdeck, the notification is a bit more obvious to users, but for Twitter web users (which account for 70% or so of all users), notifications aren't as noticeable.

To remedy this situation, this week Twitter is starting to notify its users of replies and re-tweets via email. This is a reversal for Twitter, which, until this point didn't utilize email notifications for many uses other than direct messages and new followers. Also, in using email notifications, Twitter is now using the tactic of email notifications that Facebook has utilized for years to keep users engaged.

What is your opinion -- is this a form of spam or are email notifications useful to you? Users who don't want to have notifications invading their inbox can easily turn them off via preferences on

After Negative Review and Lawsuit, Yelp Gets a Check

After a negative review was left on Yelp, the well-known site for user generated reviews on businesses and locations, a dentist filed suit for defamation against the reviewer and also sued Yelp itself. The case itself is notable because it's quite rare that a doctor sues a patient. In this instance, the court issued a split decision.

Most of the dentist's claims against the reviewer were thrown own out, while the defamation claim is still being decided upon and remains a risk to the Yelp reviewer. However, in an almost comical move, the dentist's suit against Yelp was dismissed and as a federal law immunizes Yelp and as a result, Yelp's legal fees are being paid for by the dentist.

This situation should yield two major lessons. First of all, as Yelp gains more usage, reviewers should realize that posting untrue statements can land you in trouble according to defamation laws. Also, those filing suits against sites such as Yelp should read federal code and see that in most cases, these sites are immune from such this dentist hast discovered, $80,000 later.
